 * attempt to preserve the aspect ratio.
 * <p>
 * If the region has an explicitly set preferred width and height, those are used unless
 * override is set true.
 * <p>
 * If the region already has a parent, the returned pane will replace it via the
 * {@link #replaceComponent(Node, Node)} method. The Region's parent must be a Pane in this case.
 *
 * @param region   non-null Region
 * @param w        default width, used if the region's width is calculated
 * @param h        default height, used if the region's height is calculated
 * @param override if true, w,h is the region's "100%" size even if the region has an explicit
 *                 preferred width and height set.
 *
 * @return the created StackPane, with preferred width and height set based on size determined by
 *         w, h, and override parameters.
